---------------------------------------- Bug #521: gizmosphere/gizmo2 development board VGA support not working https://ticket.coreboot.org/issues/521
* Author: 8oDE 03 * Status: New * Priority: High * Category: board support * Target version: none * Start date: 2023-12-24 * Affected versions: 4.18 * Needs backport to: none * Affected hardware: GizmoSphere Gizmo 2 ---------------------------------------- I got a gizmo2 development board. the official hardware and software support stopped a long time ago and no BIOS source code was released. I tried to compile coreboot firmware to support some new features. The latest supported coreboot version is 4.18. I flashed and booted the gizmo2 development board, there is no video output during the coreboot startup phase, but it boots the OS normally and the OS has video output, I purchased a FT232H board for printing logs, and it seems like there are a lot of problems.
